Homeschooling can be expensive. Homeschooling high school can be even more expensive. The average cost of a new high school textbook is about $70. Ouch. Today, I’m sharing a whole bunch of homeschool high school math free resources, from complete courses to textbooks to worksheets and tests that I hope you can use.

## Homeschool High School Math Free Resources

### Complete Courses

- Khan Academy – do I really need to say more? Khan has all the core high school math classes: Algebra, Geometry, Trigonometry, and Pre-Calc under the High School Math section. You can find Calculus and higher level math under the individual subjects. Be sure to signup as a coach so you get your students weekly progress reports. While Khan is setup to be self-paced, you’ll need to actively monitor your student’s progress. It’s easy to get behind, if there is no accountability. Nobody wants to makeup that math homework over the summer! Especially parents.
- CK-12 – is it’s own little educational world. Start with a free textbook; they have a large, mostly math and science, selection. Each unit contains reading assignments, videos, practice resources, real world application examples, and a downloadable quiz. CK-12 also includes a PLIX (Play, Learn, Interact Explore) assignment for the unit, which is like an interactive word problem. CK-12 is available across numerous platforms, and they also have a practice app. The website even has a “cafe” where students can ask questions and get help.
- School Yourself has “free interactive lessons from award-winning Harvard instructors.” I’m really excited by this website. Rather than learning math in a linear manner (as laid out by a textbook) SchoolYourself customizes your learning based on how you perform. It’s similar to Kahn Academy – a voice lecturing while you watch a video. But, rather than watching 10-12 minutes on Kahn and then applying the knowledge, this site acts more like an in-person tutor. You answer questions throughout the video. If you answer incorrectly, it prompts you to try again, or you can ask for a hint; if you answer correctly, then you move on. Our younger daughter just started using this to review Algebra and Geometry, and we like it so far.
- OpenCulture lists over sixty free math classes, with most being available on iTunes.
- SAS Curriculum Pathways is another free website that offers complete math courses. Students watch videos, complete practice exercises and take quizzes.
- edX has numerous math MOOC courses, from Algebra through Calculus.

### Texts & Videos

Instead of a complete course, these sites offer additional help by topic that you can use as a supplement to your math program.

- Math Planet is a free textbook and video website. While not a complete package, it looks like an excellent resource for math topics.
- Cool Math focuses on the high school math subjects of pre-Algebra, Algebra and pre-Calculus. It is similar to a math textbook, but way more understandable. The website also has lots of math games to play.
- The Free High School Science Texts: Textbooks for High School Students Studying the Sciences Mathematics Grades 10 – 12 is a 600+ page pdf math book. It states “Grade 10-12” in the title, but it covers most of high school math (Algebra, Geometry, Trigonometry). Includes exercises, but I did not see an answer key.
- Open Culture has over seventy textbooks from algebra to differential equations.

### Math Worksheet Generators

Sometimes, you just need a worksheet to check mastery of a concept or as test prep. These websites can generate math worksheets for you.

### Math Tests

- Math-Tests.com – free online math tests for pre-Algebra, Algebra and Geometry.
- Pearson Education – free online math tests for the New York Algebra Exam. I would use this website as an end of the year review.
- The Virginia Department of Education has several high school math tests that you can print and give to your students at the end of the year.

Finally, need help answering a specific math question? At Wolfram Alpha you type in an equation and it will calculate the answer for you. It will also graph the equation, and give you a step by step solution.

High school homeschool math can be a tough subject to teach. But, you don’t have to do it alone – you just need the internet and access to all these great free resources. I honestly can’t imagine homeschooling before the internet!! Can you?
